Hammer Metals regains full control of Mount Isa East tenements

Hammer Metals has announced that Sumitomo Metal Mining Oceania (SMMO) has signalled its intention to withdraw from the Mount Isa East Joint Venture. The Mount Isa East JV was originally formed with JOGMEC in November 2019, before JOGMEC’s interest was sold to SMMO in 2021. The Joint Venture originally covered four areas within Hammer’s portfolio: Even Steven, Mt Philp, Malbon and Dronfield.

Full ownership consolidation simplifies decision-making and removes JV obligations on these tenements, giving Hammer complete strategic flexibility over the areas.

What is a joint venture withdrawal in mining?

In exploration joint ventures, partners can elect to withdraw if they choose not to continue funding programmes. When a JV partner exits, their interest typically reverts to the remaining party. This is common in junior exploration where priorities shift between partners.

For Hammer, this means regaining full strategic flexibility over these tenements without ongoing JV commitments.

Exploration progress delivered under the JV

The JV programmes delivered early exploration success at the Trafalgar deposit and tested several high-quality copper-gold targets within the Joint Venture area.

Daniel Thomas, Managing Director

“We thank Sumitomo Metal Mining Oceania and JOGMEC for their participation in, and contribution to, the Mount Isa East JV. The programs delivered early exploration success at the Trafalgar deposit and tested several high-quality copper-gold targets within the Joint Venture area. Several prospective targets remain within the portfolio and have the potential to support Hammer’s stated hub-and-spoke development strategy, centred on a centralised processing facility at Kalman.”

Strategic fit with Hammer’s hub-and-spoke model

Several prospective targets remain within the portfolio and have the potential to support Hammer’s stated hub-and-spoke development strategy, centred on a centralised processing facility at Kalman.

Hammer holds a strategic tenement position covering approximately 3,600 km² within the Mount Isa mining district. The company’s key 100% owned deposits include:

  • Kalman (Cu-Au-Mo-Re)
  • Overlander North and South (Cu-Co)
  • Lakeview (Cu-Au)
  • Elaine (Cu-Au)

Hammer also has a 51% interest in the Jubilee (Cu-Au) deposit.

Hammer Metals' Mount Isa Hub-and-Spoke Strategy

Regaining these tenements consolidates ground that could feed a future central processing hub, potentially enhancing project economics.
